What a great spot!
B's condo is in a brand new building and tastefully decorated throughout, with essential comforts like wifi and AC!
The building has a beautiful infinity pool on the 49th floor overlooking the Bangkok skyline, Chaopaya river view, Old town and grand palace and even a decent little fitness room that you can use. If you're wanting to tan then the sun hits it from about 1pm through the rest of the day but in the morning it is a little in the shade.
Location is SUPER convenient for Bangkok just five minutes from the sky train. Thoroughly enjoyed my stay and would absolutely aim to stay here next time I'm in BKK without a moment's hesitation!
